Koa

Definitions

1. A minimalist Node.js web framework created by the same team behind Express, designed around async/await and a middleware stack that uses a cascading (downstream then upstream) execution model via next().

   In plain English: A lightweight tool for building web servers in JavaScript, made by the creators of the popular Express framework but with a more modern design.

   Example: "We migrated from Express to Koa because async/await error handling is so much cleaner than callback-based middleware."
